A Perforated Desk Surface to Diminish Coloration in Desktop Audio-Production Environments

In audio-production rooms, a common source of harmful reflections is the mixing console or desk surface itself. A perforated material is proposed as an alternative desk surface to reduce coloration by achieving acoustical transparency. A variety of desk surfaces and perforation schemes were tested within common room conditions. The resulting psychoacoustic study indicates that the fully-perforated desk provides lower coloration than that of the solid desk in every condition. A partially perforated desk shows a similar decrease in coloration, specifically when the perforated area is determined by the Fresnel zones dictated by the source and receiver positions.
